VGA-to-VGA DDC/EDID Emulator

This item may take 4 weeks to deliver.


The ConnectPRO DDC EDID Emulator is designed to solve the problem that computers can sometimes lose the Extended Display Identification Data (EDID). The DDC EDID data is vital for the video extension; it is a data structure provided by a computer display to describe its characteristics to a graphics card. However, when you switch or disconnect and then reconnect a display such as a monitor, you may lose DDC EDID communication and subsequently the computer may fail to display the image properly, if at all.

Now, such is no longer the case if you use ConnectPRO’s VGA DDC EDID Emulator module. The ConnectPRO DDC EDID Emulator allows the user to have best video image setting all the time. Through an easy programmed process, the display’s DDC EDID is memorized in the DDC module, thus preventing our customers from blank screens and boot problems as well as resolving the issue of display resolution and color due to a lack of DDC EDID information.

Supported Resolutions on Default Table

The preferred method is for the customer to clone the specific monitor that is to be used, but when that is not an option the customer can use the standard table built into the Ghost Emulator (the Green light setting).

Frequently Asked Questions


    • Does the display I want to use have to be cloned?

      • No. There is an alternate mode, represented by a green LED light, which feeds a profile for a standard display, with some common resolutions built-in.


  • Will the Emulator ever need to be recloned? Does it ever lose the cloned image? Does it have to be recloned after being without power for a certain amount of time?

    • The Emulator will keep the cloned image permanently until a new monitor is cloned, which effectively overwrites the initial cloned image.
